How much is your blog worth?

We found this nifty widget on the Business Opportunities Weblog. According to this widget, Where What How Why was worth $14,113.50 on April 26th. We hoped it would go up and it did. It is now worth $19,194.36. What is this quote based on? We’re not really sure, but it could have something to do with the Technorati ranking.
